Helped a friend install os8 on his XO-1. When we got done, he
decided to enter the command 'yum install gparted'. Yum failed with
a "not enough memory" error.
I happened to have an SD card with me that had a swap partition
defined on it. The XO's SD slot was already in use, so I attached
an USB card reader (with my card in it), and issued the appropriate
'swapon /dev/...' command.
Now he could issue 'rpm -e gparted' and then 'yum install gparted'
again. This time, yum was successful.
The moral: Things can be done if swap space is present that cannot
be done if swap space is not present.
